V5 series inverter
23
2-5-4. Connection of communication terminals
The communication port of this inverter is standard RS485 port.
With the following wiring methods, you can build up control system of one-host-one-slave or one-host-multi-slaves. Also,
the superior device (PC or PLC) can realize the functions such as real time monitor inverter, remote control, highly auto-
mated motion control.
Connection of inverter RS485 port and superior device:
Fig. 2-9 RS485-(RS485/232)-RS232 cable connection
Many inverters can be connected together through RS485, the PLC(or PC) is the host device, as shown in Fig.2-10;
Also, you can select one inveter as host and the other inverters are slaves, as shown in Fig.2-11.The more inverters are
connected, the communication system will be interfered seriously, the following wiring is recommended.
